Patent JP-H04308494-A (JP)
Title: Disc drive
Inventor: HOSHINO TAKAYUKI
IPC: H02P6/24
Filed: 1991-04-04
Abstract: PURPOSE:To enhance reliability and to realize cost reduction by grounding at least one of m-phase windings through a semiconductor element. CONSTITUTION:When a power supply voltage Vcc is being fed to a driving circuit 1, the driving circuit 1 feeds an AC three-phase current to a spindle motor 3 upon switching of a control signal CE from 'H' to 'L' to start rotation of the spindle motor 3 which subsequently reaches a predetermined rotational speed. When the power supply voltage Vcc is interrupted, a transistor 2A is turned ON and phase W winding of the spindle motor 3 is grounded to produce a ground current(brake current) and thereby the spindle motor 3 enters into generative brake state resulting in reduction of rotational speed. Consequently, reliability of circuit is enhanced resulting in an inexpensive circuit.

Title: Current lead
Inventor: KANEKO NORIO
IPC: H01F6/00
Filed: 1994-03-17
Abstract: PURPOSE:To protect a superconductive system entirely in safety by composing at least one conductor of a plurality of superconductor strands applied with a thermally conductive material thereby detecting abnormality of a current lead itself. CONSTITUTION:Seven conductor strands 1 (1a-1q), each comprising a silver pipe filled with Bi2Sr2Ca2Cu3Oy having critical temperature of about 105K, are stranded to produce a primary stranded conductor. The conductor is inserted into a hollow pipe of a thermally conductive material 3, i.e., aluminium, and the gap between the conductor and the aluminium pipe is filled with an amine curable epoxy resin. This structure enhances the reliability of a current lead and since the abnormality of current lead can be detected from the initial stage, trouble can be prevented for the entire superconductive system.

Title: Method for plating on metallic base material
Inventor: TAKEUCHI HIROMITSU
IPC: C23C18/52
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a plating method for metallic base material capable of suppressing the occurrence of crack and peel after formation of a plating layer. SOLUTION: A plating liquid is vigorously injected from a jet nozzle 15 and is cast to the surface of the base material 1 made of aluminum. Voltage is impressed between the nozzle 15 and base material 1 which are electrically connected by the plating liquid, by which the metal ion components in the metallic plating liquid are deposited as a metal matrix and the plating layer is formed as the jet nozzle 15 plays the role of anode and the base material 1 as cathode. The plating liquid is brought into contact with the surface of the base material 1 at the relatively high speed given thereto, by which hydrogen is hardly taken into the formed plating layer. The microscopic porous state which may arise after the formation of the plating layer is thus averted. Then, the plating layer eventually has the residual stress on the compression side.
